CU LTIVATOR ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No. 721,277, dated. February 24, 1903.

Application filed November 19, 1902. Serial No. 132,017. (No model.)

To all whom, it may concern:

Be it known that I, OMER C. BATEMAN, a citizen of the United States, residing at Taylor Ridge, in the county of Rock Island and State of Illinois, have invented a new and useful Cultivator Attachment, of which the following is a specification.

This invention relates to an improved attachment for cultivators, the said attachment consisting of a device by means of which the cultivator-gangs may be connected with the arch of a riding-cultivator in such a manner that while they shall be held steadily to their work the said gangs shall be capable of lateral movement, so that in the event of the plants growing unevenly in the rows which are to be cultivated the said gangs may be shifted in an outward direction from the rows to avoid injuring the plants.

The invention consists in the improved construction, arrangement, and combination of parts constituting the said cultivator attachment, which will be hereinafterdescribed, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view showing a cultivator-gang connected with one end of the'arch of a cultivator by means of a device constructed in accordance with the principles of my invention. Fig. 2 is a side elevation of my improved cultivator attachment. Fig. 3 is a horizontal sectional view taken on the line 3 3 in Fig. 2. Fig. 4 is a transverse sectional view taken on the line 44 in Fig. 2, but illustrating the device as in operative position.

Corresponding parts in the several figures are indicated by similar characters of reference.

My improved attachment consists of atube or sleeve 1, provided at one end thereof with aradially-extending arm 2 and at its other end with a lug 8, which is disposed on the side of the sleeve opposite to the arm 2. r

4 designates a plate having arms 5 5, forming a yoke that straddles the sleeve 1, and is pivotally connected with the lug 3 by means of a bolt 6, extending through'said lug and through the arms of the yoke. Said plate 4 is provided with a perforation or bolt-hole 7 and with a concentric slot 8 for the attachment of the cultivator-gang 9, which is socured adjustably to said plate by means of two bolts 1011, one of which is adjustable in the slot 8, thus permitting the rear end of the cultivator-gang to-be raised or lowered with relation to thepoint of attachment to the plate 4. The latter is also provided with an arm or bracket 12, extending through aperforation 13 in the arm 2 and provided with a pin 14, whereby it is prevented from withdrawing from said opening. Aspring15,coiled upon the projecting end of the arm 12 between the pin 14: and the arm 2, serves to force the hinged plate 4, carrying the cultivatorgang, in the direction of the arm 2.

The sleeve 1 is provided with a set-screw 16,

by means of which it may be secured in position upon the collar 17, mounted upon the arm 18 of the cultivator-arch, one end of which is shown at 19 in Fig.1.

The operation of this invention and its advantages will be readily understoodfrom the foregoing description, taken in connection with the drawings hereto annexed. The setsc'rew 16, by means of which the sleeve 1 is secured, admits of the adjustment laterally of said sleeve with relation to the collar'17, whichlatter is revoluble in the usual manner upon the arm 18 of the arch, so as to permit thegang to be raised or lowered. The spring serves to push the cultivator-gang in the direction of the row. Should the latter be uneven and the cultivator-blades be in danger of interfering with the plants, the gang may be forced aside against the tension of the spring, as will be readily understood, the said spring serving to restore it as soon as the pressure is released. The pressure necessary to operate the cultivator-gang against the tension of the spring may be exerted by the feet of the operator when the cultivator IOU Having thus described my invention, I claim- 1. A device of the class described, comprising a sleeve having a radially-extending arm and a log extending in the opposite di rection to said arm, a plate having a yoke straddling the said sleeve and connected hingedly with the lug thereof and a spring forcing said plate in the direction of the arm.

2. A device of the class described, comprising a sleeve having a radially-extending arm, and a hinged plate adapted for the attachment of a cultivator-gang.

3. A device of the class described, comprising a sleeve having a radially-extending arm and a lug extending in the opposite direction to said arm, and a plate adapted for the attachment of a cultivator-gang and having a yoke straddling the sleeve and connccted hingedly with the lug thereof.

l. A'device of the class described, comprising a sleeve having a radially-extending arm, a plate hingedly connected with said sleeve, and a spring forcing said plate in the direction of the arm. I a

5. A device of the class described, comprising a sleeve having a radially-extending arm and provided With a lug extending in the opposite direction to said arm, a plate having a yoke straddling the sleeve and connected hingedly with the lug thereof, a curved bracket extending from said plate through an opening in the radial arm and having a pin at its outer end, and spring coiled upon the projecting end of said arm or bracket.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

OMER C. BATEMAN.
